<h3>Answer:  175 square cm</h3>

Work Shown:

Area of square = side*side = 7*7 = 49

Area of one triangle = (1/2)*base*height = (1/2)*7*9 = 31.5

Area of four triangles = 4*(area of one triangle) = 4*31.5 = 126

total area = (area of square)+(area of four triangles) = 49+126 = 175

This total area of the net is the same as the surface area of the square prism. Imagine folding this 2D flat shape to form a 3D figure.

olga_2 [115]
First find the rate of growth
45000=18000(1+r)^(2010-2005)
Solve for r
r=((45,000÷18,000)^(1÷5)−1)×100
R=20%
Use it to find the population in 2015
P=45000(1+0.20)^(2015-2010)
P==111,974.4

"at the end of the year Juan has $52.71 more than 4 times his balance at the beginning of the year if his ending balance was $17
Salsk061 [2.6K]
At the end of the year, Juan has 52.71 more than 4 times his balance at the beginning. Okay, let's set this up.

4x + 52.71
(4 times) (52.71 more)
His ending was 172.90, so
4x + 52.71=172.90
4x= 120.19
x= 30.05
He had $30.05 at the beginning of the year.
